All numbered starting with ‘CPS-‘ they use piezo technology with a built-in driving circuit to create a range of variable tones and sounds, “including hi-lo, warble, sweeping, one-tone and six-tone”, according to the company.
Featuring sound pressure levels (SPLs) go up to 120dB, and there are through-hole, panel mount and wire lead mounting styles.
Operation is from 12 or 24Vdc and across -30 to 85°C, and nominally at 2.5, 2.65, or 2.75kHz.
Security system, medical devices and industrial applications are foreseen.
The one pictured is the CPS-5952-100PM wich runs of 24Vdc and produces 100dB at 2.65kHz. It works over -20 to 70°C and is 45 x 40 x 59mm. Termination is wire leads.
